Nebraska, have inveir'ted s. new and useful Towing Attachment for Tractors, of which the following is a specification.

This invention relates to an attachment for tractors and the like used for towing, one of the objects being to provide an attachmerit to be secured to orformed on the tractor and to which the towing cable or chain is connected, means being employed whereby the power mechanism of the tractor can be utilized to control the action of the attachment that, when desired, the tractor can 4 be relieved of. the restraining action of the towed load by poyin out the cable or chain. after which sold cab e or chain can be taken up. to return the said load to its initial position relative to the tractor.

A further object is to provide an attachment of this character which is especially useful by allowing a tractor to pass over a .;{mnd hole or the like while paying out the \.,-oable connection with th towed load after which, by winding up the said connedion, the/said load can be drawn over the mud hole and up to the tractor.

A further object is to provide an attachment of this character which will automaticolly sto winding the cable or chain when the towe load is brought to position close to the tractor.

With the foregoing and other objects in view the invention consists of certain noveldetails ofconstruction and combinations of parts which will be hereinafter more fully described and pointed out in the claims, it being understood that various changes may be made in theconstruction and combination of parts without departing from the spiritof the invention as set forth in the appended claim.

In the accompanying drawings the preferred form. of the invention has been shown.

In said drawi s Figure 1 is a. side elevation of a portion of a. tractor having the present improveto meats applied thereto.

Fig. 8 is a. piss view of s portion of the attachment and showing one means which may be used to operate the same.

Fig. 3 is an elevation of one side of the attachment.

Fig. 4 is a rear elevation thereof, a part being broken away. Fig. 5 is a. plan view of the attachment. Fig. 6 is a section on line 6-6, Fig. 5.

Referring to the figures by characters of reference,- 11 designates the frame of the attachment the sides of which are provided with depending ears or hearing members 2.

A shaft 3 is journaled in the ears 2 and secured to and revoluble with this shaft is a spool 4 provided at one end with a gear 5 and at its other end with a ratchet wheel 6. A pawl 7 is pivotally connected-to one side of the frame 1 and normally engages the ratchet wheel 6 thus to hold the spool normally against rotation in one direction. This pawl may be provided with an arm 8 whereby it can be shifted readily for the purpose ofreleosing' the ratchet wheel 6.

The gear 5 meshes with another gear 9 secured to a shaft 10 journaled in the sides of the frame 1. A clutch member 11 is secured to and rotates with this shaft and another clutch member is loosely mounted on said shaft and has been shown at 12. This clutch member 12 has 21. sprocket 13 secured thereto and adapted to rotate therewith and formed in one end portion of the clutch member 12 is an annular groove 14: into which projects the forked end 15 of a lever 16. The outer end of the lever is extended laterally from the frame 1 where it can be asped and operated readily.

slida 'hly mounted in the back end of the frame 1 are the side arms 17 and 18 of a depending loop 19 constituting a push head which is arranged-back of the frame 1.- The free end of theorm 17 is connected by a. spring 20 to the back end of the frame 1,

thus to hold said loop or head 1.9 pressed backwardly away from the frame The forward end of the other arm 18 1s oifs'et I obliquely as at 21 and extends between the speei a A i Peon, 521d cables passlzzg built into irac'bor 1e1ei ii any desired oint.
